Empowerment plugin "Free Attribute calculate price"

Hello, webdesigner! In the plugin "Free Attribute calculate price" has the ability to set a different formula and the ability to validate input numbers for multiple categories. I've got one of the categories there are six of goods. Each product has its own formula and the range of the entered digits. Is there a possibility to set different formulas and validation, and for goods? And another question:is it possible to increase the number of fields for ID free attributes ?
